I love the screen-shots, but I fear doing this properly is something which GtkTreeView can't do. In an application I'm working on, I would really love to use a row which spans columns for the purpose of rendering a: "Click here to add new field" row. I unfortunately ended up having to put a (much shorter) text in the first column. I get the feeling that too much of GtkTreeView's implementation is private to be able to subclass it and provide this additional functionality, not to mention that its rendering model is very specific to columns. I think a brand new widget might be needed - one which has a more "table" like rendering model. It might be possible to start from GtkTreeView's code - but its a scary "C" file, and I quickly realised I didn't have the time / knowledge to write the new widget myself.
